il) @ZZ whom Z5 may concern:

it known that, l, Annan) D. MAURY. citizen of the United States, andresident of vlion. in the county of Herkimer and State is releasable ina novel way and to such a' position as to facilitate the introduction ofpaper into the machine.

Another object is to provide novel releasing and locking devices for thepaper table and deiiector and for the paper feed rollers of themacl'iine.

Another object is combine the releasing' operations of 'the nove' papertable and delector and of the feed rollers so that these elements may bereleased concurrently and locked in released position.

Other obiec's will hereinafter appear.

To the above ends invention consists in the ieaturl of construction,combinations of'dcvit arrangements of parts and particularly pointed ontin 1n the accompanying drawings which illustrate one form of mysaidinvention as applied to the platen. carrier of a llo. 10 Ren'iingtonfront strike typcwriting machine. Figure 1 z.- fragmentary bottom plan'View of the platen and platen carrier showing my invention appliedthereto. Fig'. 2 is a side elevation of the platen and platen carriageshown in Fig. 1. the left-hand finger wheel heine' sectioned away. Fig.3 is a transverse sectional View, taken on a plane represented by thedotted line :n .r in Fig", 1

Dig

in the di roction of the arrows fiector and table locked off in releasedposition. Flg.v 1s a fragmentary front View,

`partly in section, showing certain of the releasing and lockingdevices.

In the drawings the platen 1 is supported on an axle 2 which bears inthe end bars or plates 3 of a plat-en frame or carrier which furthercomprises a cross bar l extending under 'the platen lengthwise thereofand connecting the end bars. Secured by screws 5 to the front of thecross bar 4 are a plurality of angular supporting arms or brackets t3,said arms extending upward from the bar 4 and thence rearward over thesame.

and between it and the platen and terminatingin enlarged portions whichare bored out, to provide bearing openings for a rod orA ported in acarrier or holderwhich com-A prises side arms 9 and 10 and a connectingcross arm 11, the said arms extending horizontally rearward and beingperforated to permit of the passage therethrough of the rod 7, theroller carriers bearing loosely on said rod.. -The arm 9 has a downwardear or extension 12 against which abuts a lip 13 projecting laterallyfrom a hook-like member 1 which has an' open slot 14a adapting` it tohook over and bear on the rod 7 close to the arm 9, as clearly shown inFigs. 1' and 4. The hook-like member 14 extends downward below the lip 13 and has connected to its the rear end of a coil spring lfsaid springextending forward and being anchored to an opening in the cross bar el.rihe construction is such that the spring` 15 constantly tends to drawthe hook 1 4 forward and transmits its pressure through the lip 13 tothe eXtension 12 of the feed roll carrier and thence to the feed roller,the latter being thus maintained normally in Contact with the platen orthe paper thereon by the spring 15. The hook 14;, it will be observed,is a. pressure transmitter and s but' two of them, this ligureillustrate platen carrier as broken off at about of its ,length so thatonly about and of the vplaten is disclosed. with each feed rollercarrier is .5f w. l@ which is pnmed at 17 or otherwise secured 'to therock shaft 7 and normally if, overl the cross bar l1 but is separatedan, as shown in Fig. el, so that when T is rocked, as hereinafter delarm L ll will cooperate with the bar lll to "I irce the carrier to swingdownward apai the spring l5 and move the feed roller to released orinoperative position.

i l, lr mounted on the rock shaft 7 near nach l thereof is a supportingbracket compr 3 end portions 18 and 19 and a V3@ connor i cross-bar 20,the end portions hearing on the rock shaft 7. The bracket portion i8 isangularly shaped, comprising an up ardly and forwardly extending arm 2lwh terminates in a lateral lip 22 and 5 furthe comprising a downwardextension .vhicn is connected by a coiled spring 24 with the cross barel.' A releasing member or arm L?, pinned or othe-rwise secured at 2b tothe rock shaft 7 and extends upward ard therefrom, overlies the'lip 22pled to cooperate therewith when the shaY l' is rocked, to swing thesupporting brarltet 18-20 on its pivot. The supporting,brackets justreferred to, of which as has been stated there are two, support thelower end portions of a combined paper table and paper detlector memberwhich is ign-ated as a whole by the numeral Q8, tiaid member 28 hasndetlector portion Q9 which lies close to theplaten and is curved toconform to the shape thereof rather closely at the front underside ofthe platen. the dellector portion 29 tdrminating at ,the front of themachine somewhat below the j: n'inling line and close to the face of theplaten. The dellector portion 29 is slotted, as indicated at Q9, toprovide openings thrrmgh which the feed roller sections 8 may moretoward and away from the platen. The paper table portion 30 of thedeflector extends upward and rearward away from the platen at thereaiside thereofv and terrhinates at a considerable distance above andhehinifi the platen. The lower portion of nce four are en'iployedalthough Fig. l-

member in the form of an arm the combined. member 28 has secured to itnotiamo near each end, as by rivets 31 (Fig. l) or otherwise, an angularbracket 32- which is pivotally connected at 33 with the upper endportion of the arm 21 of the associated supporting bracket 18--20. Theupper portion of the combined member 28 is supported at about midwayofits length, the supporting devices comprising an angular bracket 84which is rivetedat 85 or otherwise secured to they rear face of themember 28 and provides a rearwardly extending ear 36 to which is screwedor otherwise secured at 87 a slotted member ork guide 38,v the slot 39of said guide being elongated and receiving a cross rod l0 which issecured at its ends to rearward extensions 8a on the end bars of theplaten carrier. The slot 89, it will be observed, is downwardly andforwardly inclined at an angle of something like (30 from thehorizontal, and the disposition of the pivots or pins of the connection88 with respect to the axial center of the rock shaft 7 is such thatthey will move downward and forward when operated as hereinafterdescribed, in a path parallel substantially with the angle of the slot99. Consequently the combined paper table and delector will have what iscommonly referred to as a parallel motion, that is, points or partsf ofit will move in parallel paths.

In order to release the feed roller and the combined paper tableand'detlector, means are provided comprising a crank arm lll which has ahub Ll2 screwed at 43 to the rock shaft 7 outside the left-hand end bar3 (Fig. l). The crank arm ll normally extends forward and upward, asshown in Fig. 2, and is pivotally connected at let with the lower end ofa member l5 which is in the nature of-an eccentric strap, the upper endof the member being enlarged, as indicated at 46, and being providedwith a circular opening in which lits an eccentric boss 47 projectinginward from lthe lower end portion of an eccentric member 48, saidmember having an upward extension which is twisted to provide a fingerpiece or releasing device 49. rl`he eccentric member 48 bears on aheaded shouldered screw 50 which has a shouldered bearing portion and areduced threaded portion which screws into a tapped opening in an upwardextension 3b of the left-hand. end bar 3 and is locked in place by acheck nut 5l (Fig. 6). Inter-posed between the head of the screw 50 andthe outer face of the member 4-8 is a cupped washer 52 which is heldunder tension against the outer face of the member 48 and exertsfriction tending to oppose the turning of said member. As will vbeapparent from a consideration of Figs. 2, 5 and the eccentric' proper 47is mounted eccentrically of the axis of the screw .'70 so that when theeccentric member 48 is turned the eccentric proper will co-act withtheerator pushed the linger piece 149 rearward.

lbody portion of the member 4S is cut away to provide stop shoulders 53and ,i'which co-act with a lateral stop pin on the strap /l-se to limitturning movements of the eccentric member.

Figs. 2 3 and lillustrate the normal positions oi the various parts.Referring,T to these iigures it will be observed that the eccentricdevices are positioned or set through the co-action of the stops 53 andthat the :teed rollers are engaged with the platen and that thedetlector 29 is also engaged therewith at the t'ront lower sidethereoi'; also that the pivotal supporting points are above and forwardof the axis 7 while the lower portion of the guide slot 39 is incooperation with the guiding and supporting rod e0. Suppose now theoptrom the Fig. Q to the l? 5 posit-ioni This operation lowers theeccentric proper-` l?, causing the saine to move the eccentric strapdownward, the movements Acontinuing until the parts are arrested by theco-action ot the stop with the .stop pinna. This brings the eccentricynearly on a dead center and owing to this tactand also partly to the'friction ot the washer 52, the parts will he nniintained set or lockedin the Fig. 5 position. The downward movement of the eccentric strap'turns the crank arm di downward and forward, rocking the shaft i in thesaine direction and causing the t with the cross arms il, 'as

lil to co heretofore described, to release the feed rollers Si".toncurrently the arms will act against the. lips to rock the supportside-20 agr' it the. springs 2st, this movement ot said supports causingthe pivotal connections 33 to swing' downward and forward andcommunicating the parallel motion aforesaid to the combined paper tableand dcdector, the upper end 'of which is guided and controlledduring'this movement by the inclined guide siotn) and the (zo-acting,`guide rod'or fixed elementfelO.

he movement communicated to the combined paper table and detlector iscomparatively'slight and yet results in a movement ot the deiiector awayfrom the platen' in what may be termed a radial direction so that asshown in Fig. and as indicated by dotted lines in Fig. "2, an opening ofsubstantially uniform Width is provided at. the under and forward sidesot the platen through which one or ay considerable number ot sheets otpaper may be readily inserted and guided smoothly and withoutobstruction forward under vthe platen and upward in the direction ot theprinting point at the front side thereof. The advantage of thus bodilyYreleasing' the detlector and moving it to an abnormal position inl whichit is substantially concentric with the platen will be apparent whencompared with prior constructions in which the delector is swung orrotated around a single pivot in suchl a way that when released, insteadot being substantially concentric with the platen, its forward portioninclines toward the platen so as in away to ,obstruct the advance of thepaper as it wasinserted, this' disadvantage' being especially markedwhen more than one sheet, or what is termed a pack, required insertionand adjustment. The parts are restored to normal .positiongby pullingthe linger piece t9 forward from the Fig. 5 to the Fig. 2 position.

it will further be observed `that by my present invention I provide incombination with' a platen, a paper guiding device which has a papertable portion and a paper defleeting portion; that the paper detlectoris curved to conform substantially to .the

curvature of the platen; that means are provided tor affording movementotsaid delector away Jfrom the pl'aten such that the points or parts ofsaid deiiector follow sub stantially straight parallel paths; that themovement of the deiicctor away fromtheplaten ipa bodily movement asdistinguished from affmere movement around a pivotal center, al of theparts or points moving substantially the same extent; that by themovement of the deflector from the platen a substantially uniformopening is obtained which in the present instance is at the under andforward sides of the platen; that the paper device or member is ni,vably supported at tivo points one above the other, said points beingat the rear ot the platen; that the movement of the device 'is in aninclined path down ard and forward relatively to the platen; that meansare provided for locking or maintaining the device in released orabnormal position; that in released or abnormal position the delector issubstantially concentric with the platen; and that a. paper controllingdevice or feed roller is associated with a pressure transmitter which inthe present in-- stance is a member let which operates as a lever,transmitting spring pressure between the feed roller or controllingdevice.
